Greatest Common Divisior
We found the divisors of 693, 123, 78, 935 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 693, 123, 78, 935 is 1.
Therefore, GCD of numbers 693, 123, 78, 935 is 1
Given Input Data is 693, 123, 78, 935
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 693 is 3 x 3 x 7 x 11
Prime Factorization of 123 is 3 x 41
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 935 is 5 x 11 x 17
The above numbers do not have any common prime factor. So GCD is 1
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(693, 123) = 28413
GCD(693, 123) = ( 693 x 123 ) / 28413
GCD(693, 123) = 85239 / 28413
GCD(693, 123) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 78
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 78) = 78
GCD(3, 78) = ( 3 x 78 ) / 78
GCD(3, 78) = 234 / 78
GCD(3, 78) = 3
Step3:
Here we consider the GCD from the above i.e. 3 as first number and the next as 935
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 935) = 2805
GCD(3, 935) = ( 3 x 935 ) / 2805
GCD(3, 935) = 2805 / 2805
GCD(3, 935) = 1
GCD of 693, 123, 78, 935 is 1
